Bad hair transplants, also known as failed or unsatisfactory transplants, occur when the surgical procedure results in an unnatural or undesirable appearance. A prime example is the "doll's hair" effect, where the transplanted hairs appear overly dense and stiff, giving the patient an artificial look.
Hair transplantation has gained immense popularity as a treatment for hair loss, offering benefits such as improved self-esteem and a more youthful appearance. Historically, the technique originated in Japan in the 1930s and has since undergone significant advancements.
